Checking and cleaning MAF sensors

[lufkin]

mine seems to have no power some times, cleaned the mac but no difference. forgot to do reset though. second gear foot flat it just goes nowhere if revs are low. this normal?

You have probably already checked but it's an easy mistake. I cleaned my MAF and had no power after wards. Was stumped for a few min then realised I hadn't re plugged it in

this is not quite true some efi vehicles had a MAP sensor (Manifold Absolute Pressure sensor).
cheers mav

My bad, wasn't thinking, "clunk"

Thank you YNOT! I have a problem, I could not find the sensor cleaner in the market over here... I live in Bolivia. Would you know of anyother "cleaner" that would do the job?

Hi all, Does anybody have some idiot proof instructions and advice for me on how to clean the MAF on a 1999 2.8.
Is it the same thing a the 3.0 info that YNOT kindly posted in this thread or something different ?
Please excuse ignorance - just learning, and thanks in advance for any info !

What if the red wire voltage reading is 13.8v?
That's what mine does. White is on 12 V which is the same as the battery voltage

Thought I had a MAF problem & acquired an engine management booklet. Free. Goodee.
Wiring diagram didnt show GU IV & then i realised YNOT had the colors worked out. Thank YNOT. Thought I was going to buy a MAF until I sorted the wires & colors out. Nissan want an exceptional quantity of $$$.
